Job Description

About the Role

This is an early, high-ownership engineering role at a seed-stage vertical AI startup building autonomous tooling for the global freight and logistics industry. You will join a small founding team in Munich to design, build, and scale the core product, shaping technical direction from the ground up. The role combines hands-on full-stack engineering, production AI/ML work, and real product ownership.

What You'll Do

  • Own and personally design, build, and maintain the most critical parts of the product.

  • Build reliable full-stack features that make users radically more efficient.

  • Evaluate, benchmark, and fine-tune AI capabilities to maximize domain accuracy and context.

  • Continuously experiment with new model releases, frameworks, and agentic techniques in production.

  • Ship promising approaches quickly and iterate based on data and user feedback.

  • Navigate and improve large-scale, complex legacy code to add structure and scalability.

  • Engineer infrastructure and automation to support heavy data and AI workloads.

  • Collaborate closely with founders and teammates as a hands-on, high-ownership contributor.

What We're Looking For

  • Practical, hands-on experience with AI/ML and LLM systems: benchmarking, fine-tuning, and running experiments in production.

  • Strong full-stack engineering skills with fluency across backend and cloud environments.

  • Fluent in Python; familiarity with Go is a strong plus.

  • Domain knowledge in logistics or freight forwarding.

  • Evidence of building robust, real-world production systems.

  • Comfort working with complex legacy codebases and engineering for scale.

  • Strong CS fundamentals, intellectual humility, and exceptional self-discipline.

  • 2 to 3 years of professional experience, or equivalent through relevant projects or a demonstrable track record.

  • Prior startup or entrepreneurial experience, with a results-oriented and autonomous work style.

  • Strong spoken English sufficient for fluid technical discussion.

  • Willingness to work on-site in Munich or to relocate there.

Compensation & Benefits

Salary range: 60,000 to 90,000 EUR annually. Equity participation via options (up to 1%, with top-ups possible). Visa sponsorship is not available.

Location

On-site in Munich, Bavaria, Germany. This role requires regular in-person presence; remote work is not an option.
